This invention relates to a vaporizer of the type bottom 15 of thecontainer and the bore of the I used in the treatment of diseases of therespiraspout conununicateswith the air spout 14 through tory tract andhas for an object to provide a anopeni'ngzt.

When thevalve plunger is wide open the vapor pressure and density is at itshighest volume and when the valve is adjusted to less than wide openposition the vapor volume and density is diminished accordingly.

Since the operation of the parts has been described as the descriptionof the parts progressed it is thought the invention'will be fullyunderstood Without further explanation.

What is claimed is: e s

An atomizer containing a liquid container having a vapor outlet,'asiphon tube in the'container having a tapered inlet end disposed in theliquid,

the container having the outlet and terminating in atomizing relation tothe outlet end of the and forming a check valve to retainvliquid in thetube to a predetermined height, an air spoutin siphon tube, meansconnected to the intake end of the air spout for forcing air underpressure from the spout in the path of liquid drawn from the siphontube,a tubular seat in the Wall of the container terminating near the outletend of the air spout, there being oppositely disposed air intakeopenings in the seat externally of the container, and a, tubular valveplunger closed at the outer end and open at-the inner end =rotatablymounted in said seat, the plunger having oppositely disposed openingsadapted to cooperate with the air intake openings in the seat.
